Pipeline is the main manner to transport oil and gas from one place to another. Oil-gas pipeline is built rapidly in the last decade in China. At the same time oil-gas pipeline accident threatens the person's live and property. Corrosion is one of the main reasons that affect the oil-gas pipeline safety operation. Pipeline corrosion damage quantitative risk analysis is carried out on the basis of pipeline function equation and detecting data. The effect of the related parameters uncertainty on the analysis results is resolved by Monte-Carlo method. Then risk value of the pipeline segment is gotten. It has significant meaning to the safety management of oil-gas pipeline. A sample is given to show that: ①pipeline corrosion damage risk analysis on the basis of pipeline function equation and detecting data eliminates the subjective factor to assessment outcome, and improve the objectivity of the risk analysis; ②Monte-Carlo method can resolve the problem of the uncertainty of data, including operation parameter, detecting data etc; ③the pipeline with defect can keep safe by decreasing the operation pressure.
